What is Bobbin?
Bobbin is an AI productivity tool that gives your AI assistants a searchable memory of what you browse, built for people who research across many tabs and want ChatGPT or Claude to recall it. The Chrome extension indexes pages locally as you read: it captures article text, YouTube captions with timestamps, PDF content with page links, tables, image captions, and your own highlights. You can then search that library from the Bobbin panel, the side panel, or straight from the address bar with the "cx" command, and ask questions that come back with citations to the source page. An Assistant Sync feature writes your indexed content to Google Drive so AI tools can read it, and you can export notes as Markdown or back up and restore the whole library. Processing happens on your own device, with no Bobbin account or server involved, and the extension deliberately skips banking, health, and email sites plus incognito windows. You stay in control: pause indexing, block specific sites, or delete individual pages at any time. For anyone building a personal knowledge base to feed an AI assistant, Bobbin is a practical, privacy-first option worth a look on a BestAIFor shortlist.
